Hey guys,

I research lots but somehow was not able to find propper info.

Ok, this weekend, i was installing my LCD car alarm, but ran into some trouble. I have an 05 f250 crew cab v8 gasoline ( no factory keyless entry or chip in key)

1 issue---I wired the siren fine however i want to wire also the horn of the truck. I did notice the horn wire (dark blue) in truck has 12v constant and in order for it to make sound a neg charge or ground needs to be applied. Now, how can i wire for it to sound? perhaps a relay? and if so how can i wire it? meaning 87 where , 30 where? in relay......the alarm output cable gives a positive charge when activates to siren......(would a flasher need to be installed?) how can i wire it? thanks sorry if its too much to ask....

2nd issue-i cannot find the positive trigger cable and negative trigger cable(someone told me might be on driver kick panel)
*can you provide me also with a link for a good wiring diagram of my truck? thanks
thanks let me know please.... looking to install remote start but that would come in after i get basics

3rd issue-i need to run a remote wire for my amps in truck, where can i run it off , so that when i turn on radio, it turns on the amps? (1st time running a remote wire sorry)

thanks a lot for all your help.........

help............anyone??

 

i am alarm illiterate (i had mine installed for me)

as for the remote wire. you can run a small wire from the radio, and hook it to a wire that is labeled antenna or you might have an amp wire

The horn relay is simple. Your alarm will be the trigger and applies power to the relay's coil. Alarm + into coil, ground the other side of the coil. Ground the center pin of the coil and rub the switch on side to the horn wire.
